It is demonstrated how the RF Module of COMSOL Multiphysics® can be used to approximately model thin conducting wires or cables and how they interact with a surrounding electromagnetic field. Despite being non-stringent the method can reasonably well predict currents induced by an ... En savoir plus
The aim of this work is to compute the mechanical forces in a 12-pulse converter transformer winding in different short-circuit modes. A 12-pulse converter transformer is a three phase transformer with two secondary windings whose tension have 30° phase displacement and one primary ... En savoir plus
In the nuclear industry, and particularly at Framatome, mastery of welding processes is essential. Framatome is one of the world leaders in this field and wants to improve even more. The work presented focuses on improving the TIG (Tungsten Inert Gas) welding process, and more ... En savoir plus
In the present study we determined the relative conductivities and permittivities of fresh cortical and cancellous bone measuring human femoral heads in different slices of 1 mm thickness. The identified conductivities of human trabecular bone are used for the electromagnetic field ... En savoir plus
In microwave heating applications, the energy is introduced directly into the volume of the material and as consequence the quality of the process is highly dependent on the uniformity of the electromagnetic field distribution along it. That is, the non uniformity of the heating is a ... En savoir plus
In this study, a detailed finite element model coupling the motion dynamics and electromagnetics of a diaphragm based MEMS vibration energy harvester is presented. The energy harvester converts low frequency vibrations to high frequency response by magnetic actuation of a diaphragm ... En savoir plus
Resistive magnets are one of the principal components of ion medical accelerator systems used in heavy ion cancer treatment. To fulfill medical requirements, like the size of irradiation field and an uniform dose distribution, some magnets of the transport beam line may require large ... En savoir plus
Eddy current thermography (ECT) is a non-destructive contact-free method of defect detection in a conductive material combining the electromagnetic induction of eddy currents and thermal imaging. This technique uses an excitation system consisting of an inductor with coil(s) carrying ... En savoir plus
In this work, a 2.8x0.22 μm^2 silicon strip waveguide (n = 3.43 @4.234 μm) on a silica substrate (n = 1.38 @4.234 μm) and a superstrate with n = 1 was designed and evaluated through 2D (i.e., mode analysis), and 3D (i.e., wave propagation) analysis to strengthen the interaction between ...

The contamination of food products with low water contents is a safety issue that cannot be disregarded. Despite their low water activity, they are indeed susceptible to infection by micro-organisms that are highly resistant to heat. In this case, conventional pasteurisation techniques ... En savoir plus
